Exceptions and Errors raised by QAlgebra.

Summary

Exceptions:

AlgebraError	Base class for all algebraic errors.
AlgebraException	Base class for all algebraic exceptions.
BasisNotSetError	Raised if the basis or a Hilbert space dimension is unavailable.
CannotSimplify	Raised when a rule cannot further simplify an expression.
CannotSymbolicallyDiagonalize	Matrix cannot be diagonalized analytically.
InfiniteSumError	Raised when expanding a sum into an infinite number of terms.
NoConjugateMatrix	Raised when entries of Matrix have no defined conjugate.
NonSquareMatrix	Raised when a Matrix fails to be square.
OverlappingSpaces	Raised when objects fail to be in separate Hilbert spaces.
SpaceTooLargeError	Raised when objects fail to be have overlapping Hilbert spaces.
UnequalSpaces	Raised when objects fail to be in the same Hilbert space.

__all__: AlgebraError, AlgebraException, BasisNotSetError, CannotSimplify, CannotSymbolicallyDiagonalize, InfiniteSumError, NoConjugateMatrix, NonSquareMatrix, OverlappingSpaces, SpaceTooLargeError, UnequalSpaces

Reference

exception qalgebra.core.exceptions.AlgebraException

Bases: Exception

Base class for all algebraic exceptions.

These should only be used for internat signaling, and never be raised to a user.

exception qalgebra.core.exceptions.AlgebraError

Bases: ValueError

Base class for all algebraic errors.

exception qalgebra.core.exceptions.InfiniteSumError

Bases: qalgebra.core.exceptions.AlgebraError

Raised when expanding a sum into an infinite number of terms.

exception qalgebra.core.exceptions.CannotSimplify

Bases: qalgebra.core.exceptions.AlgebraException

Raised when a rule cannot further simplify an expression.

exception qalgebra.core.exceptions.BasisNotSetError

Bases: qalgebra.core.exceptions.AlgebraError

Raised if the basis or a Hilbert space dimension is unavailable.

exception qalgebra.core.exceptions.UnequalSpaces

Bases: qalgebra.core.exceptions.AlgebraError

Raised when objects fail to be in the same Hilbert space.

This happens for example when trying to add two states from different Hilbert spaces.

exception qalgebra.core.exceptions.OverlappingSpaces

Bases: qalgebra.core.exceptions.AlgebraError

Raised when objects fail to be in separate Hilbert spaces.

exception qalgebra.core.exceptions.SpaceTooLargeError

Bases: qalgebra.core.exceptions.AlgebraError

Raised when objects fail to be have overlapping Hilbert spaces.

exception qalgebra.core.exceptions.CannotSymbolicallyDiagonalize

Bases: qalgebra.core.exceptions.AlgebraException

Matrix cannot be diagonalized analytically.

Signals that a fallback to numerical diagonalization is required.

exception qalgebra.core.exceptions.NonSquareMatrix

Bases: qalgebra.core.exceptions.AlgebraError

Raised when a Matrix fails to be square.

exception qalgebra.core.exceptions.NoConjugateMatrix

Bases: qalgebra.core.exceptions.AlgebraError

Raised when entries of Matrix have no defined conjugate.
